ROBINSON, OFPARKERSBURG, WEST VIRGINIA GHANGEABLE EXHIBITOR Application fi1ed August7, 1928. Serial No. 298,009.

This invention relates to new and useful improvements in changeableexhibitors and has particular reference to that character of exhibitoradapted to be employed in 'conj unction with street cars, buses and thelike and includes generally a casing having a trans parent front wallthe back of which is movable and indicating strips having variousdestination marks thereon visible through the transparent wall of thecasing so that said markings may be readily viewed to inform those aboutto board the street car or busas to the particular destination of thevehicle.

An object of this invention is to provide a device of this characterwhich is very simple in its construction and inexpensive of manufactureand one that embodies but few parts to be so co-related as to reduce thepossibility of disarrangement to a minimum. 7

With the foregoing and other objects in View as the nature of theinvention will be better understood, the same comprises the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawings and claimed.

In the drawing wherein like reference characters indicate correspondingparts 0 throughout the several views:

Figure 1 is a front elevation of our improved exhibitor,

Figure 2 is a top plan View thereof,

Figure 3 is a detail longitudinal transverse section,

Figure 4E is a longitudinal section taken at right angles to Figure 3,

Figure 5 is a rear elevational View,

Figures 6 and 7 are enlarged fragmentary vertical sections takensubstantially on the line 6-6 and 77 of Figure 3, and

Figure 8 is a perspective of one of the strip guide pins.

Now having particular reference to the drawings, our novel exhibitorconsists of an elongated casing 5 of suitable material open at its frontside and provided at said open side with a pair of longitudinally spacedglass panels 6-6, the ends of the innermost 0 panel terminating slightlyinwardly of the end walls of the casing as more clearly illustrated inFigure 3.

, Spacing strips (J-@ are secured to the top and bottom walls of thecasing intermediate the adjacent longitudinal edges of the panels 6 forretaining these panels in spaced relation. Additional retaining stripsZ) are likewise secured to the top and bottom walls of said casing inlongitudinal spaced relation to the spacing strips a and between thecorresponding strips a and Z) is received the upper andlower marginaledges respectively of the innermost transparent panel 6 as shown toadvantage in Figure 7. As also shown in this figure, the strips (1 andpanels 6 define a longitudinally extending guideway c in which guidewayis movable .an exhibitor strip 11, which strip 11 will be hereinafterdescribed more in detail.

The rear wall ofthis casing 5 is provided with a suitable hinged door 7so thataccess maybe hadto theinterior ofsaid casing.

Mounted vertically within this casing 5 adjacent the end walls thereofare roller shafts 8.-8, the lower ends of which extend through thebottom wall of the casin and are constructed at said lower ends toprovide suitahle turning handles 99.

Secured to these pins are flanged belt rollers 1010 while secured tothese rollers at the opposite ends of an indicating belt or strip 11 ofpredetermined length, said strip or 'belt being provided throughout itslength with varied destination markings as disposed in Figure 1. I

Preferably the strip or belt is of nontransparent material. and theletters forming the various designations are of a transparent materialso that lightrays within the casing will proj ect theret'hrough.

At the ends of the innermost glass panel 6 there is arranged verticallyextending guide pins 1212 over which the strip or belt is trained andpassing between said panels 66 as clearly illustrated in Figure 3.

Obviously the arrangement of the strip or belt between these panels 66will maintain the same in flat like condition so that the designationshown may he clearly viewed.

Mounted within the casing 5 in back of the visible portion of the beltor strip are a plurality of electric lamps or illuminating means 13-13.Obviously by rotating the handles 99 of the roller shaft 8-8 the stripor belt will be rolled from one roller on to the other causing themovement of tl e strip or belt between the panel 6-6 so that variousindications may be brought to light between said glass panels.

10 In view of the forego ng descrlptlon when considered 111 conjunctionwith the accompanying drawings it will be apparent that we have producedhighly novel, simple and exinely useful changeable exhibitor that iswell adapted for all of the purposes heretodesignated.

Even though we have herein shown and describec. the invention asconsisting of certain detail s uctural elements, it is nevertheto be un'derstood that minor changes may be n de therein without affecting thespirit and scope of the appended claims.

Having thus described our invention, what we claim as new is:

1. In a changeable ez-cnibitor, a. casing having an open front andincluding top and bottom walls, a transparent panel closing said openfront, spacing strips secured to the top and bottom walls engaging theinner face of 0 said transparent panel, a second transparent panelarranged in rear of the first mentioned panel and engaging said stripsand terminating short of the ends of the first referred to panel, saidstrip and said panels defining 35 a longitudinally extending guideway,illuminating elements arranged within said casing, vertically disposedrollers mounted for rotation within said casing adjacent the oppositeends of said casing, means for rotating said 40 rollers, an exhibitorbelt traversing said rollers, said belt being movable in said guidewayand said belt having indicia characters formed thereon, said indiciacharacters being formed of transparent material.

2. In a changeable exhibitor, a casing open along one side thereof, apair of spaced apart transparent panels arranged in said casing andclosing said opened side, a pair of spaced apart strips arranged betweensaid panels and constituting with said panels adjacent said open side ofthe casing a guide passage, and an indicia carrying strip movablethrough said guide passage, said panels being of unequal length, andguide rollers for said strio at opposite ends of said guide passage,their being one guide roller adjacent each end of said shorter of saidpanels.

In testimony whereof we aflix our signatures.
